Marked synovial thickening is seen in the fourth and fifth extensor compartments with a large amount of fluid and multiple bodies within the tendon sheaths. The bodies are uniform in shape and show moderately high T2 and isointense T1 signal intensity. Enhancement of the thickened synovium is noted in the post-contrast images.
No erosive changes could be seen. A small split tear of the extensor carpi ulnaris tendon is noted. The rest of the extensor tendons are unremarkable. The TFCC, intrinsic and extrinsic ligaments around the wrist are grossly unremarkable. The flexor tendons, ulnar and median nerves are unremarkable.
